These 6 quests can be done every day quite easily for some extra experience, however, there is an even bigger use here.

LindsayOld MacDonald and Dagra the Fierce are special. They're quests give exp AND are account wide. The big advantage here is you can park some alts next to each one, log in, beat the quest, log out, then log onto the character you actually you want to get the experience and profit. This works great for characters like monks who you can keep safely parked in a town with their +50% exp buffs.

Another advantage for the Pet Battlers out there is that these pet battlers are all fairly low in level. You can open up with a level 1 pet swap out to a strong pet and stomp the team. Great experience for your lowbie pets and great experience for an alt!
